Hazardous Waste is created when there is no further use for a solid or liquid chemical. This waste is our responsibility from when we create it — until forever. This is described as being from "Cradle to Grave". Therefore, proper documentation is important whenever waste is picked up and disposed of.
What is hazardous waste?
Hazardousl waste is, used, obsolete or unwanted chemicals such as: acids, bases, aerosol cans, paints, solvents, batteries, photographic film, and cleaners.
Nothing — including mop water, paint, oil, chemicals, etc. — should be dumped outside on the ground, into outside storm drains or into building floor drains. Waste put in storm drains and floor drains eventually ends up in our rivers and oceans. The best practice is to pour mop water down sink drains that go directly into the sanitary sewer system. Hazardousl waste should be disposed of by calling EH&S at 6-8591.
